The AT4 Premium Package adds the Off-Road High Clearance Steps, giving you an easier way in and out without sacrificing ground clearance on the trail. The AT4 suspension package, skid plates, red recovery hooks, auto-locking rear differential, and hill descent control round out the off-road hardware.
For the hitch, the Preferred Equipment Group 4SB brings a full Trailering Package with an integrated trailer brake controller, in-vehicle trailering system app, trailer side blind zone alert, and hitch view — plus trailer camera provisions so you can wire in a trailer-mounted camera. The spray-on pickup bedliner with GMC logo protects the bed from day one.
Inside, the perforated leather front seats are heated and ventilated, and the second-row outboard seats are heated as well. A power rake and telescoping steering column, remote vehicle starter, keyless open and start, push button start, wireless charging, a 120-volt interior power outlet, and a floor-mounted center console with USB ports keep the cabin practical and comfortable on long drives.
The 13.4-inch diagonal premium GMC Infotainment System with Google built-in apps, wireless Apple CarPlay and Android Auto, and the Bose 7-speaker premium sound system handle connectivity and entertainment. The Technology Package layers in a rear camera mirror, a multicolor 15-inch diagonal head-up display, and a bed view camera — so backing into tight spots and monitoring the load are both easier.
A power sliding rear window, rear-window defogger, universal home remote, front rain-sensing wipers, and deep-tinted glass round out the comfort and convenience story. The sunroof and engine block heater are on this unit as well, and 20x9 machined aluminum wheels wear 275/60R20 all-terrain tires.
GMC Pro Safety covers forward collision mitigation, rear cross traffic braking, rear pedestrian alert, ultrasonic front and rear park assist, and HD Surround Vision. SiriusXM with 360L, a Wi-Fi hotspot, and OnStar connected services complete the technology story.
